• [x ] bug report -> please search issues before submitting
• [x ] feature request

As suggested by the article "You might not need to transpile your JavaScript" if one is targeting modern browsers than es6 should work as a target.

Versions.

Angular 4.3.6
Angular cli 1.3.2

Change target in tsconfig.json to "es6"

ng build --bh /ui/ --prod --aot

ES 6 target should build (and work in a modern browser)
